Albion vice-captain Jonas Olsson has insisted the team will not suffer a Carling Cup hangover when they return to Championship action on Saturday.

The Baggies suffered their first defeat of the season at Arsenal on Tuesday, but their unbeaten league record remains intact heading into the Hawthorns clash with Crystal Palace.

Olsson insists defeat at the Emirates Stadium will have no bearing on Saturday’s match, which could see Roberto Di Matteo’s men equal a club-record nine-match unbeaten start to a League campaign.

The defender said: “Tuesday won’t affect us in the League –you have to look at how we played. We weren’t smashed at Arsenal.

“We played a great team with 10 men. We showed that we’re in good shape.”
